Hi all, my goal is to align two slightly different categorization systems where each categorized item can have multiple categories in one of these systems.
E.g.: Categorized item: "Harry Potter" Category system 1: Fiction, Fantasy, Children Category system 2: Youth, Fantasy The alignment would then produce a similarity between "Fantasy" (used in both systems) and "Children" (1) and Youth (2). I *think* ItemSimilarity is what I want but if anyone can provide me with the correct keywords for googling - that would be great. If a Lucene/SOLR index is more efficient as source than the lists I have I'm fine with setting that up. However, I am not sure how the schema would have to be structured? Would it use the categorized items as document entities - if not what then? Any pointers where to start would be very much appreciated! Also the information whether I need a full Hadoop installation or whether Mahout as checked out from trunk is sufficient. It is not very much data altogether (<10k categorized items). Thanks! Chantal
